the electromagnetic spectrum 1. A laser emits light of frequency 4.74 104 s. What is the wavelength of light in nm? 2. A certain electromagnetic wave has a wavelength of 625 nm. to. What is the frequency of the wave? b. What region of the electromagnetic spectrum is it in? c. What is the energy of the wave in Joules? (Hint: the energy equation is as follows: E = hv) BONUS: 5 pts 3. How many minutes would it take for a radio wave to travel from the planet Venus to Earth? (Mean distance from Venus to Earth = 28 million miles). 4. The blue color of the sky is due to the scattering of sunlight by air molecules. Blue light has a frequency of approximately 7.5 x 1014 Hz. Calculate the wavelength, in nm, associated with this radiation. 5. Calculate the frequency and energy of blue light that has a wavelength of 400 nm. 6. First calculate the frequency of light that has a wavelength of 4.25 x 10-9 m and second identify the type of electromagnetic radiation.
